FOLDING UMBBELLA;

pp'lica'tion led May 9,

The present invention relates to an uinbrella Whi'ehoan beclosedup in` length to aboutv oneftount-l'r of its actual dimensions. It; iS, .tibi-1s possible to lpackthe shortened uniblellaintoya case. orwallet and carry it conveniently 'in-a 'travelling or hond bag'with outvvbeing inconvenienced .by the otherwise usual long stick.

The invention Consists substantially in div id-inl,both.l fthe stick and the ribs of the umbrella. longtudinallyl and making these parts capable of bein-g folded together by means of hinges, 'which can be locked by the provision of suitable means when the stick and the ribs are extended. A further iiinprouenient inthe present invention is that thesehinges canin "eachvoase be closed up in one direction only but are rigidon Vthe side so thatthe strength of the umbrella isr thereby increased.`

The subject matter of the present invention-,is Villustrated in the accompanying drawing but numerous variations inay be made in the l,choice of the hinges and the means ors'tift'ening them Without departing troni the essential feature of 'the present invention. f

In o'ider til yC'onneot the different parts of S5 the stick "rigidly to each other When in 'the extended position means Vare provided for enabling the joints to lbe vlocked in this ositio'n. 'For 'this purpose theie are p'iovifv'ed' on vthe 'solid parts a, b' o tufo tubesojr 9U sleeves z" `and 2 which Vsurroiind thein and which canw lbe so pushed along on the parts of the stick vvthat they release the joints so that Ythese latter vcan be turned dovtinfor they eover up lthe extended joints .Yandjs'ur- 95 round 'thorn and so` lock them. The Inova-- bflit'y 'of these tubes yon the dider'entparts oft tbe stick lis so limited t'hatth'ey cannet be inoved beyond Certain positions, Aand in partieular so that the joints are just released sufiiiei'ently or covered up so as to simplify the use of the umbrella. The

CFI

limitation of the movement of vthe tubes z" and 2 may be eiiected by fixed stops such as rivets for example, or by stop pins lo, or integral projections on the stick which slide in suitable longitudinal slots Z in the tubes j in the tubes whereby they prevent these latr brella stick.

" sions that when the umbrella stick is extended and locked they abut against each other and in a way form a continuous tube.

The ribs of the umbrella can be folded up longitudinally in the same way as the um- They each consist therefore of two parts 0 and 02, which, as shown in Figs. 8 and 9 are pivotally connected together. member p to which the parts o and o2 of the ribs are pivoted by means of pins g. Owing to the link member p being U-shaped in cross section and closed underneath, the joint can again bey closedon one .side only namely outwards, while in the opposite direction it acts rigidly beyond the extended position. lTopprevent the outer rib o2 from swinging round, the mouth r of the link is made elastic so that it will catch over the cross section of the rib parts 0 and 02 elastically and hold them securely in the extended position. The link may of course also lie inside the U-shaped rib so that its mouth catches elastically over the pivots and projecting ends of the link.y

The constructional form of the umbrella is in other respects the same as in an umbrella of the ordinary kind. Struts s are pivoted on the one hand to the ribs o and 0n the other hand to a sleeve adapted to slide on the stick i. e. the ordinary runner so as to enable the cover of the umbrella to be opened out as shown in Fig. 6. The ribs o are likewise. pivoted in the usual way toa crown u which however is of dierent construction than the type hitherto emn ployed. lt is screwed to the tube z" so that the point a of the stick can pass through it when the stick is extended. Furthermore the crown plate to which the pivots fu for the ribs 0 are attached is made of such The joints each consist oi a link say towards the ribs o-'while the runner t with the struts s is pushed upwards yunder the cro-wn u (see Fig. 4l). To open the umbrella the stick is first extended straight out and then the handle CZ held Vand the two tubes pushed together over the places where the joints are in the stick, after which the springs n, n and n2 are snapped into their slots, while the stop pins la vstrike against the ends of their guide slots Z, Z2.

After the stick has been thus extended andv locked the runner t is brought into its usual position over the springs'nf, n2 on the handle CZ and the ribs o2 then turned down with the cover a@ attached to themuntil the links p have snapped into place. The umbrella can then be opened 'in the usual way. j

I claim l. An umbrella, embodying a stick which comprises a plurality of'sections jointed together at their ends for pivotal movement into and out of mutual alinement; locking tubes slidable on said sections to cover and uncover the joints; means for limiting vthe movements ot' the tubes so disposed that in' one extreme position the joints are just exposed, while in their other extreme position the tubes completely cover the joints; and catches, independent of said 'limiting means, for holding the tubes in the secondnamed extreme position. f

2. An umbrella, embodying a stick which comprises a plurality of sections jointed'tm gether at their ends for pivotal movement into and out of mutual'alinement; locking tubes vslidable on said sections to cover and' uncover the joints and provided with'lon gitudinal slots; stop pins fixed to said sections and projecting into said slots to limit the extent of movement of the tubes, the slots having a length such that in one ex treme position of the tubes the joints are just exposed, while in their other extreme position the tubes completelyV cover the joints; and catches, independent of said stop pins, for holding the tubes inthe sec:L ond-nained extreme position.
